So far, extremely disappointed in this new BIOS. I used to be able to overclock my 2600K to 4.6Ghz rock solid but now with any overclock applied (even if I put VCore and VCCIO higher than they used to be), I get Code 55 POST errors. System says my Corsair Vengeance RAM supports XMP Profile 1, Code 55 when I enable it. If I set it to defaults, it detects it at 1333Mhz, even though it's 1866Mhz. Manually set it 1866Mhz, Code 55. Basically, this BIOS "upgrade" rendered this board useless for overclocking. It appears I'm far from the only person having this issue and there's been silence from EVGA. I'm hoping someone else has figured out a solution. But yeah, this is likely the last EVGA product I'm buying. I like to support more specialised brands but I never had a BIOS upgrade degrade performance on an Asus or Gigabyte board.
